Comparative Analysis of the Old MWHGL and the New NAPTF Data
(American Society of Civil Engineers, 2007)The new generation of aircraft will require more landing-wheels to be packed into basically the same space. A convincing illustration of the move to more densely packed landing gears is the recent Boeing B777, which has ... -
Crashworthiness of Motor Vehicle and Traffic Light Pole in Frontal Collisions
(American Society of Civil Engineers, 2006)The mitigation of severe problems resulting from vehicle collisions with roadside objects has become one of the major research areas in automotive engineering. The literature review shows that few attempts in finite-element ... -
Study of In Situ Pavement Material Properties Determined from FWD Testing
(American Society of Civil Engineers, 2006)The Vermont Agency of Transportation (Agency) developed pavement design procedures patterned after the American Association of State Highway and Transportation Officials (AASHTO) pavement design model described in the -
Simplified Solution for Periodic Thermal Discontinuities in Asphalt Overlays Bonded to Rigid Pavements
(American Society of Civil Engineers, 2007)This work investigates the elastic fields which develop in an overlay bonded to a rigid substrate when the system is subjected to thermally induced stress. A two-dimensional solution of the displacement field is derived ... -
Modeling the Probability of Freeway Rear-End Crash Occurrence
(American Society of Civil Engineers, 2007)A microscopic model of freeway rear-end crash risk is developed based on a modified negative binomial regression and estimated using Washington State data. Compared with most existing models, this model has two major ... -
Developing Combined Genetic Algorithm—Hill-Climbing Optimization Method for Area Traffic Control
(American Society of Civil Engineers, 2006)This study develops a genetic algorithm with TRANSYT hill-climbing optimization routine, referred to as GATHIC, and proposes a -
Estimation of Uniform Delay of Permitted Left Turns from Exclusive Turn Lanes
(American Society of Civil Engineers, 2006)The -
Geometric Models to Calculate Left-Turn Sight Distance for Signalized Intersections on Horizontal Curves
(American Society of Civil Engineers, 2006)At signalized intersections where protected left turn signals are not provided, simultaneous opposing left-turn vehicles may cause insufficient sight distance for each other. There is a lack of literature presenting left-turn ... -
Relationship between Speed, Lateral Placement, and Drivers’ Eye Movement at Two-Lane Rural Highways
(American Society of Civil Engineers, 2006)A number of previous studies have investigated driver behaviors including speed and lateral placement in curved sections of highways. However, few studies attempted to empirically address relationships considering other ... -
Comparison of Modeling and Measurement Accuracy of Road Condition Data
(American Society of Civil Engineers, 2006)The condition of a road network and its deterioration rate can be estimated by using measurements and statistical models. The purpose of this paper is to provide tools for assessing the accuracy of the condition information ... -
Assignment of Seasonal Factor Categories to Urban Coverage Count Stations Using a Fuzzy Decision Tree
(American Society of Civil Engineers, 2006)Seasonal factor is an important parameter for converting coverage counts to annual average daily traffic (AADT). There have been many studies on establishing seasonal factor (SF) categories, but there is a limited understanding ... -
Deployment of Fiber Optic Networks through Underground Sewers in North America
(American Society of Civil Engineers, 2006)The demand for broadband communications is exploding in North America. Two decades of cable laying has resulted in a national backbone of high-speed data network. However, a gap remains; a gap between the metropolitan area ... -
3D Calculation of Stopping-Sight Distance from GPS Data
(American Society of Civil Engineers, 2006)Sight distance is a key element in highway geometric design. Existing models for evaluating sight distance are applicable only to two-dimensional (2D), separate horizontal, and vertical alignments or simple elements of ... -
Safety Analysis of Florida Rural Interstate Freeway Travel in Relation to the 65 km∕h (40 mi∕hr) Minimum Speed Regulation
(American Society of Civil Engineers, 2006)The relevance of posting the -
Application of Cement-Based Piezoelectric Sensors for Monitoring Traffic Flows
(American Society of Civil Engineers, 2006)In this paper, the preliminary application of a new type of cement-based piezoelectric sensor developed recently for monitoring the traffic flows is proposed and investigated. The sensor was made by bonding between two ... -
Effect of Coarse Aggregate Morphology on Permanent Deformation Behavior of Hot Mix Asphalt
(American Society of Civil Engineers, 2006)This paper defined a complete set of imaging based indices for different levels of coarse aggregate morphologies, i.e., the flat and elongated (FE) ratio, angularity index (AI), and surface texture (ST) index, and investigated ... -
Validation of a Model for Predicting Schedule Changes in Highway Work Zones—Case Studies
(American Society of Civil Engineers, 2006)There are currently no standard or accepted methods in the construction industry to calculate the probable impact of indirect cost factors on the schedule of highway work zone projects. This paper presents a model for ... -
Overtaking Rule Method for the Cleaning of Matched License-Plate Data
(American Society of Civil Engineers, 2006)In recent years automatic number plate recognition systems have been increasingly used to monitor urban link travel time. However, the set of travel times produced will contain erroneous records for a variety of reasons ... -
Analytical Procedures for Estimating Capacity of Freeway Weaving, Merge, and Diverge Sections
(American Society of Civil Engineers, 2006)The paper identifies a total of 34 different weaving section configurations that are modeled while operating at capacity using the INTEGRATION software for a wide range of weaving section lengths and travel demand ... -
Development of an Optimization Methodology for Adaptive Traffic Signal Control at Diamond Interchanges
